Check Digit Verification of cas no

The CAS Registry Mumber 194350-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,3,5 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 194350-71:
(8*1)+(7*9)+(6*4)+(5*3)+(4*5)+(3*0)+(2*7)+(1*1)=145
145 % 10 = 5
So 194350-71-5 is a valid CAS Registry Number.

Copper-Mediated Diastereoselective C-H Thiolation of Ferrocenes

Kong, Wei-Jun,Shao, Qian,Li, Ming-Hong,Zhou, Zeng-Le,Xu, Hui,Dai, Hui-Xiong,Yu, Jin-Quan

, p. 2832 - 2836 (2018)

The first copper-mediated diastereoselective C-H thiolation of ferrocenes has been developed. A chiral oxazoline directing group with tert-butyl substituent is essential to the high diastereoselectivity ratio and the suppression of overreaction of monothi

Oxazolines as Dual-Function Traceless Chromophores and Chiral Auxiliaries: Enantioselective Photoassisted Synthesis of Polyheterocyclic Ketones

Mukhina, Olga A.,Kutateladze, Andrei G.

supporting information, p. 2110 - 2113 (2016/03/05)

2-(o-Amidophenyl)oxa- and -thiazolines undergo excited-state intramolecular proton transfer (ESIPT), generating aza-o-xylylenes capable of intramolecular [4+2] and [4+4] cycloadditions with tethered unsaturated pendants. Facile hydrolysis of the primary p

Chiral primary amine catalyzed asymmetric epoxidation of α-substituted acroleins

Li, Jiuyuan,Fu, Niankai,Zhang, Long,Zhou, Pengxin,Luo, Sanzhong,Cheng, Jin-Pei

experimental part, p. 6840 - 6849 (2011/03/19)

1,1-Disubstituted terminal alkenes remain challenging substrates in asymmetric epoxidation reactions. In this study, chiral primary amines are shown to catalyze the asymmetric epoxidation of α-substituted acroleins, a versatile type of 1,1-disubstituted t
